Details
This methodology note outlines the approach used to benchmark capital expenditure (CAPEX) for gas fired power plants with post combustion carbon capture and storage (CCS).
The benchmarked data informs techno-economic assumptions for future deployment scenarios of gas CCS plants.
The analysis supports the generation cost modelling undertaken by DESNZ, by providing comparative cost data for retrofit and new-build capture installations.
